⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attacker to execute arbitrary code with highest privileges, leading to data theft, system destruction, or lateral movement.
Likely Case
Privileged user uploads malicious payload leading to remote code execution within the application context, potentially compromising the SAP system.
If Mitigated
With proper access controls and monitoring, exploitation attempts are detected and blocked before successful compromise.
🎯 Exploit Status
Exploitation requires privileged user credentials to upload malicious content; deserialization vulnerability could be leveraged for RCE.
